buried in the Via Ardeatina, near the cemetery of Domitilla. Meanwhile, Zoe was hung to the branch of a tree and a fire was kindled underneath her feet, and she was killed. Nicostratus and five others were drowned in the Tiber. Tiburtius was thrown into a ditch and buried alive. Veneration The bodies of Marcus and Marcellianus were moved, probably during the ninth century, to the Church of Santi Cosma e Damiano. They were discovered there in 1583 during the reign of Pope Gregory XIII. The bodies remain there in a tomb, near an ancient painting of the two martyrs with a third person, who appears to be the Virgin Mary. In 1902, their basilica in the catacombs of Saint Balbina was rediscovered.
